【正文】 ts ( customer requirements ) using the process map as the primary source ? Key outputs are scored as to importance to the customer ? Key inputs are scored as to relationship to key outputs ? Results :Pareto of key inputs to evaluate in the FMEA and control Plans ? Results :Input into the capability study step in the measurement phase ? Results :Input into the initial evaluation of the process control plan Six 6s Sigma Cause Effect Matrix Step ? Identify Customer requirements ( outputs ) from Process Map ? Rank order and assign priority factor to each outputs ( usually on a 1 to 10 scale ) ? Identify all process steps and materials ( inputs ) from the process Map ? Evaluate correlation of each input to each output ?low scale :changes in the input variable ( amount,quality,etc ) have small effect on output variable ?High scale :changes in the input variable can greatly affect the output variable . ? Cross multiply correlation values with priority factors and add across for each input C E Matrix Six 6s Sigma R a t i n g o f I m p o r t a n c e t o C u s t o m e r10 9 9 8 31 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Finished DimensionHardnessHardness DeppthScaleDiscolorationT o t a lP r o c e s s S t e p P r o c e s s I n p u t1 S T A M P I N G R a t i n g 9 7 5 1 1 2092 D i e S e t s / I n s e r t s 5 1 1 1 1 793 P r e s s S t r o k e 9 3 1 1 1 1374 O p e r a t o r s 3 1 1 1 1 595 P r e s s S p e e d 1 2 1 1 1 486 07 H e a t T r e a t T e m p e r a t u r e 8 8 7 3 3 2488 T i m e 8 8 7 1 2 2299 B a t c h s i z e 8 8 8 1 2 23810 C o o l i n e g s y s t e m 1 9 4 1 5 15011 F u r n a c e A t m o s 2 3 6 7 2 16312 013 P l a t i n g T i m e 10 1 1 1 1 12914 B a t h T e m p 6 1 1 1 1 8915 B a t h S i z e 7 1 1 1 1 9916 017 M e x i c a l i P l a t e d P a r t s 9 3 3 1 1 15518 019 020 00T o t a l860 504 423 176690 0 0 0 0 0 0 0 0 0C au se an d Effe ct M atr i x5 .

Black Belt A process improvement project team leader who is trained and certified in sixSigma methodology and tools and who is responsible for project execution. Mater Black Belt A person who is an “ expert ” on Six Sigma techniques and on project implementation,master Black Belt play a key role in training and coaching of Back and Green Belts. Green Belt Six Sigma role similar in function to Black Belt but length of training and project scope are reduced to two weeks of training. Six 6s Sigma Key Terms Yellow Belt Hourly personnel trained in the fundamentals of sixsigma who assist and support in project execution ,usual work with black and Green Belt. Process Map A stepbystep pictorial sequence of a process showing process inputs,process outputs,cycle time ,rework operations,and inspection points. Key process Inputs Variable (KPIV) The vital few input variables,call “ x” s Key process outputs Variable (KPOV) The output variables,call “ x” s DFMA Design for manufacture and assemble, A methodology to reduce product plexity and design around more capable ponents / processes Cost of poor quality Cost associated with Providing poor quality products or services.
